Yes, I’ve tried it… It’s nice, but it doesn’t do what I described above. Thank you though.
Custom coding is what I meant. That’s why I need help. Some guidance. I searched online, but couldn’t find anything useful. If someone can point me the right direction, I would appreciate it! Maybe a website I haven’t found or some bits of code to get me started…

I will decrease the width of the admin bar to match my site’s width and I’ll create a second bar as a background. The second bar won’t have any functions, it will just have the same color as the admin bar and its width will be 100%, so it’s gonna look seamless. I haven’t done that yet, but I’m thinking to use the first linked @chouf1 posted as a guide.

What I want from you guys is to help me in the first step. I managed to decrease the admin bar’s width, but it’s aligned to the left. How can I align the whole bar to the center??

Hey @chouf1. I need to ask you something (again). Or anyone who knows… 😉

As I said before, I need to add another bar behind the admin bar. I thought to use the link you mentioned above. The HTML and the CSS code are pretty clear, but where in the child theme should I put this code?

I tried to put it in the functions.php (see image below) but it didn’t work… :/
